Blackfire Player natively integrates
Blackfire profiler. To use Blackfire Player with Blackfire profiler, add
--blackfire-env option to your
blackfire-player command. You may use
either the environment name or its UUID:
blackfire-player run scenario.bkf --blackfire-env="Environment name"
Instead of using the
--blackfire-env CLI option, you may set the
Blackfire environment in the scenario;
1 2 3 4
scenario name "Scenario Name" # Use the environment name (or UUID) you're targeting or false to disable blackfire "Environment name"
To use Blackfire Player together with Blackfire Profiler, you need to correctly setup your client credentials, which are available at https://blackfire.io/my/settings/credentials
If you have installed the Blackfire CLI, ensure that you have run the
blackfire client:config at least once to create the
~/.blackfire.ini file where your credentials are be stored.
Alternatively, you can also set
BLACKFIRE_CLIENT_TOKEN environment variables before running the
The Blackfire Player creates a build to group all the scenarios. Each scenario contains profiles and assertion reports for requests made in each step of the executed scenario.
All requests are profiled by default. You can disable the profiler in a
step or in a complete scenario by setting
1 2 3 4 5 6 7 8 9 10 11
scenario name "Scenario with Blackfire" # Use the environment name (or UUID) you're targeting or false to disable blackfire true # ... scenario name "Scenario without Blackfire" # You can disable Blackfire support on the scenario, or only on some steps blackfire false # ...
All the assertions defined in
.blackfire.yaml are automatically run
alongside Blackfire Player expectations.
You also may add assertions within a step with
1 2 3 4
scenario visit url('/blog/') name "Blog homepage" assert main.peak_memory < 10M
You can use assertions variables, defined in the Blackfire environment, like you would do within assertions defined in .blackfire.yaml file:
1 2 3 4 5 6
scenario # no Twig template compilation in production # not enforced in other environments visit url('/blog/') name "Blog homepage" assert main.peak_memory < 10mb * var('memory_coeff')
To make some comparisons with a previous build, you can set the
external_parent_id settings of the build by passing
1 2 3
BLACKFIRE_EXTERNAL_ID=current_build_reference \ BLACKFIRE_EXTERNAL_PARENT_ID=parent_build_reference \ blackfire-player run scenario.bkf --blackfire-env=ENV_NAME_OR_UUID
samples instruction tells Blackfire Profiler how many samples must be
aggregated for a single profile. The default value is
warmup instruction tells Blackfire Profiler whether to warmup the
requested URL first.
Its value can be:
1 2 3 4 5 6
scenario visit url('/blog/') name "Blog homepage" assert main.peak_memory < 10M samples 2 warmup true
